Occurrence data from AVH |
Acacia omalophylla, also known as yarrany or yarran, [1] [2] is a shrub or tree of the genus Acacia that is native to the eastern states of Australia from south central Queensland to northern parts of Victoria. [3] It has also been introduced into India and Pakistan. [4]
Acacia homalophylla has a clean trunk and leafy head, a dark gray, rough bark, narrow, usually straight leaves, and yellow flowers in balls. The leaves are edible and used for fodder. [5] It usually flowers in August–October, sometimes November.
It yields a gum. [6] Its wood (called myall-wood) is durable, fragrant, and dark-colored, and used by Indigenous Australians for spears. [7]
The tree or shrub can grow to a height of 7 m (23 ft) and has an erect or spreading habit and is often suckering. It has glabrous branchlets that can be slightly hairy on new growth and are angled at extremities. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, grey-green phyllodes have a narrowly elliptic or oblanceolate or more or less linear shape and are straight to slightly curved with a length of 4 to 11 cm (1.6 to 4.3 in) and a width of 4 to 7 mm (0.16 to 0.28 in). Many have longitudinal veins that are usually obscure but occasionally there are three or more that are more prominent. [8] The inflorescences occur in groups of one to three in the axils and have spherical flower heads with a diameter of 4 to 6 mm (0.16 to 0.24 in) and contain 20 to 30 bright yellow-coloured flowers. Following flowering firmly papery to thin leathery seed pods form that are straight and flat with a length of up to 7 cm (2.8 in) and a width of 3 to 7 mm (0.12 to 0.28 in). [8]
It has a scattered distribution through Queensland, New South Wales and Victoria. In New South Wales it is found to the west of Muswellbrook and Emmaville and is often a part of Casuarina cristata , rosewood and box communities growing in brown earthy soils. [8]
